Sense battery drains quickly

[AllieH22]

I bought a brand new Sense less than a month ago. For the first 2 weeks, the battery lasted 4-5 days before it needed a charge. Now, it's less than 2 days to go from 100% battery to 0%. I haven't changed anything about the apps, clock face, or my usage. I even deleted apps I don't use. To head off any questions, I do not have the SpO2 clock face. I don't have an inordinate amount of notifications. Clock face is set to dim. As I mentioned, I have not changed anything about my Sense since I've owned it, but the battery is just now becoming very problematic.

Any help would be appreciated.

Did you get a firmware update? It brings with it the SpO2 Tracker app which is the same as using the SpO2 clock face and reduces the charge available by about 2 days.

For starters try restarting the watch, try a different clock face and remove the SPO2 tracker app, but then you won't get that information anymore.

Its unlikely that a battery will retain 50% less charge after only 2 weeks so something else must have changed - you should expect 4.5 days with the SpO2 tracker app loaded [instead of the 6+ days without it].

See the article on extending battery.

Hi,

This morning my 3 month old Sense dropped to 82% charge in about an hour. Last night it dropped from 82% to totally flat overnight. It appears that the battery is not working as designed. Does anyone have any suggestions or having the same issue? Any assistance would be appreciated.

Hi @Teecher 

Its a fault with the Fitbit App.

Till it's fixed try turning off Bluetooth on the phone whenever you don't need.it., at least overnight.

Super annoying because you can't then use your notifications or  other features normally..

Guy,
Thanks for the information. I’ll give it a try. The battery had drained another 25% in the last two hours.

I am having exactly the same issue. 100% charge to 0% in a few hours. Worked fine for 6 months and now this issue.

There's a known iOS Fitbit App problem, so probably not a watch problem.

Have a look at these posts it may apply and can help in the mean time.

Hi all,

Since updating the firmware to version 44.128.4.17 my battery has been behaving normally. The firmware can checked via the Fitbit app. Simply go to Account, Help and Support and Check for Sense update. Hope this helps fix the issue for others also.

Thanks for the info!! I hope this works, mine started acting up a few days ago.

Just checked and mines already updated ☹️

Same... Don't you live spending good money on new tech and having it completely fail with no answers or concern from the company?

Hi all,

 I also did a factory reset to get mine working well again. Have you tried that? If you have the latest firmware and app updates there aren’t too many other options other than turning Bluetooth off on your phone. To my way of thinking that’s very unhelpful. In my case I have a number of other things that use Bluetooth and I am not prepared to turn off Bluetooth for my Sense.

Fixed mine. I removed the app from my I-phone. Charged the sense to 100% then reinstalled the app and re connected. That seemed to work. Before my battery was losing about 1% every 15 minutes. Its been back up for about an hour and still shows 100%
